摘要：Do all exporters benefit the same from export promotion programs? Surprisingly, no matter how obvious this question may a priori be when thinking of the effectiveness of these programs, there is virtually no empirical evidence on how they affect export performance in different parts of the distribution of export outcomes. This paper aims at filling this gap in the literature. We assess the distributional impacts of trade promotion activities performing efficient semiparametric quantile treatme...

摘要：Substantial attention has been paid in recent years to the risk of maturity mismatch in emerging markets. Although this risk is microeconomic in nature, the evidence advanced thus far has taken the form of macro correlations. We evaluate this mechanism empirically at the micro level by using a database of over 3000 publicly listed firms from fifteen emerging markets. We measure the risk of maturity mismatch by estimating, at the firm level, the effect on investment of the interaction of short-...

摘要：Utilizing the data I collected on a nationally mandated school meal program in India, I examine the extent to which children benefit from the targeted public transfer. Relying upon built-in randomness in whether a child's 24-hour food consumption recall was for a school or non-school day, I find that the daily nutrient intake of program participants increased substantially by 49% to 100% of the transfers. The results are robust to the potential endogeneity of program placement and individual p...

摘要：This paper examines the relationship between teacher unionization, student achievement and teachers' pay using a cross-section of data from private schools in India. We use differences in student mark across subjects to identify within-pupil variation in achievement and find that union membership of the teacher is associated with reduced pupil achievement. We find no evidence this could be due to the unobservables not controlled for by this procedure. A school fixed effects equation of teacher...

摘要：We describe a two-sector, general-equilibrium model of productive sorting under output risk and incomplete information. Risk-neutral (entrepreneurial) individuals can either produce alone, or - acting as employers/insurers - team up with risk-averse (non-entrepreneurial) individuals. Although the latter option has the potential to generate more surplus, when effort is unobservable and risk is high, the moral hazard problem in mixed matches may be too severe for mixing to be attractive to both ...

摘要：We present a model of one-way product cycles in international trade. Firms develop new product varieties in technologically advanced countries (the North), other firms copy these products in less developed countries (the South) and all shifts in production go from North to South. What distinguishes this paper from the earlier literature are the model's implications for economic growth and wage determination. Economic growth is characterized by weak scale effects, in contrast to the strong scal...

摘要：We utilize a unique pair of experiments to isolate the ways in which reductions in asymmetric information alter credit market outcomes. A Guatemalan microfinance lender gradually started using a credit bureau across its branches without letting borrowers know about it. One year later, we ran a large randomized credit information course that described the existence and workings of the bureau to the clients of this lender. This pairing of natural and randomized experiments allows us to separatel...

摘要：Vietnam's economic boom during the transition to a market economy has centered on very rapid growth in some sectors and provinces, yet poverty has diminished across the entire country. With capital investments highly concentrated by province and sector, geographic labor mobility may be critical in spreading the gains from growth. Conversely, rising income inequality may be attributable in part to impediments to migration. We first use census data to investigate migration patterns and determina...

摘要：The paper contributes to the measurement of poverty and vulnerability in three ways. First, it proposes a new approach to separating poverty into chronic and transient components. Second, it provides corrections for the statistical biases introduced when using a small number of periods to estimate the importance of vulnerability and transient poverty. Third, it applies these tools to the measurement of chronic and transient poverty in China using a rich panel data set that extends over 17 year...

摘要：This paper reports the results of the first study that estimates households' private demand for cholera vaccines using the travel cost method. We take advantage of an unusual natural experiment. In January 2004, more than 41,000 residents from various locations in Beira, Mozambique received two doses of oral cholera vaccine free of charge during the first vaccination trial to test its effectiveness in an endemic cholera zone of Africa. About 30,000 people participated from outside the target z...
